We have the Genie DVR with 3 mini receivers. When the main box and an other receiver are on the same station, the picture and sound on the main box blinks off and back on but are good on the mini. Have reset the system multiple times but keeps happening.

We see a lot of "been there, done that" replies to the reset everything suggestion. Often the poster figures he's done enough resets. The exercise we suggest is to reset the main Genie, then while it's booting up, reset each of the clients. Just wanted to make sure you had followed the proper procedure.
